SPECIFICATION forming part of Letters Patent No. 755,431, dated March 22, 1904.

Application filed April 26, 1901. Serial No. 57,554. (No model.)

To all whom it may concern.-

Be it known that we, JOSEPH N. AUsrIN and MILAN D. FARNAM, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Cutting Apparatus, of which the following is a specification.

Our invention has for its object the production of a cutting apparatus particularly applicable for comminuting meat and other food which is simple in construction, is readily assembled, and is durable and effective in use; and to this end it consists in the combination, construction, and arrangement of the component parts of a cutting apparatus, as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming part hereof, in which like letters indicate corresponding parts in all the views.

Figure 1 is' an elevation, partly in section, of our improved cutting apparatus. Fig. 2 is an end elevation of a portion of said apparatus. Figs. 3 and L are sectional views taken, respectively, on lines 3 3 and A L, Fig. 1. Figs. 5 and 6 are isometric views of the outer and inner cutting-plates. Fig. 7 is an end View of the detached forcing member. Figs. 8 and 9 are elevations of portions of the handle and the frame.

Our cutting apparatus consists, essentially, of a frame A, a forcing member B, and cutting-disks C D.

The frame A is preferably provided with a feeding-passage (0, having a flaring inlet a, suitable means a for attaching the frame in position and holding the same stationary, and a hub (0 alined with the feeding-passage a and provided with a peripheral enlargement a at its outer end. Said passage a usually increases outwardly in diameterand is provided with a socket a opening therefrom and with internal feeding-ribs a, terminating at the inner side of the exit of said passage and of the socket 64 I As best seen in Fig. 1, the forcing member B generally extends longitudinally within the passage a, is provided at one extremity with one or more substantially helical feeding ribs or blades 6 and with peripheral faces 5 b and an extension 6 and its opposite extremity is extended beyond the outer face of the hub and is formed angular in cross-section. The part of said forcing member provided With the ribs or blades 5 extends beyond the outer ends of the ribs a, and the outer portions or ends of the ribs 5 are formed of greater diameter than the corresponding ends of the ribs (1, and are movable between said ribs (0 and the cutting-plate C, presently described, and across food-receiving openings in said plate. By extending the forcing member B beyond the outer ends of the ribs (0 and forming the outer portions or ends of the ribs or blades 6 of greater diameter than the corresponding ends of the ribs a a maximum amount of food fed to the outer ends of the ribs a is discharged from the feeding-passage a with a minimum exertion, and a minimum amount of food remains in said feeding-passage when the operation of. the machine ceases. The face 6 extends through the plate C and forms a bearing for said plate. The face Z)? engages the inner face of the plate C and prevents outward endwise movement of the forcing member B independently of the plate "C, and the extension 5 cooperates with a nut 6 to prevent inward endwise movement of the forcing member independently of said plate C and to secure the plate D, also presently described, to the forcing member, the inner portion of said extension being preferably formed angular in cross-section and the outer portion thereof being threaded and extending beyond the outer face of theplate D. The extremity of the forcing member B projecting beyond the outer face of the hub a is received in a passage 5 of angular cross-section formed in a suitable handle B, is usually provided with an open-ended and open-sided socket b, which receives the enlargement of of the huba and is formed with shoulders b for engaging opposite surfaces of said enlargement, and thereby preventing endwise movement of the handle B relatively to the frame A.

The plates C D are arranged side by side and are formed with cutting edges 0 d and with openings c d for the passage of the material. The inner plate Q is substantially ring-shaped, is arranged at the inner side of the exit of the feeding-passage, and is prevented from rotation and inward and outward endwise movementby an arm 0 thereon projecting into the socket a and engaging the side and inner and outer walls thereof, and the outer plate D is formed with an opening d of angular crosssection for receiving the inner portion of the extension Z2 and is engaged by the nut 5 which is movable on the threaded outer portion of the extension 6 against the outer face of the plate D and serves to regulate the amount of r friction or tension between saidipl'ates G D. It will be understood that the plate C and the arm 0 thereof fit sufficiently loosely within the inner end of the feeding-passage and the socket a to permit the insertion and removal of said plate'C. The inner face of the plate D is generally formed with a socket d of slightly greater diameter than the contiguous surface-of the forcing member B.

In assembling the parts of our cutting apparatus the handle B is placed in position, with the enlargement to within the socket 6. The forcing member B is arranged within the feeding-passage a and is moved endwise for engaging its extremity of angular cross-section with the handle B. The plate C is placed upon the member B, with its arm 0 in the socket ai The plate D is arranged upon the extension 6 and the nut 72* is clamped against said plate D. As the forcing member B is rotated the plate D fixed thereto is revolved at the-outside of the plate C, which is held stationary by the arm 0 and the feeding ribs or blades 5 force the material lengthwise of the forcing member through the plates O D, and thus comminute said material, which escapes through the openings of said plate D.

The construction and operation of our invention will now be readily understood uponreference to the foregoing description and' the accompanying drawings, and it will be obvious to those skilled in the art that more or less change may-be made in the component parts thereof without departing from the spirit of our invention. 7

Having thus fully described our invention,

what we claim as new, and desire to, secure by Letters Patent, is

1. In afood-cutter, acasing, ashaft mounte therein, a handle removably connected to said shaft by an angular socket at one end, a segmental fiange extended from said handle concentric with said shaft, and a rigid projection 3, A cutting apparatus comprising a sta-v tionary frame provided with afeeding-passage having internal'ribs terminating at the inner side of the exit of the feeding-passage, a forcing member rotating within the feeding-pas sage and having one extremity extended beyond the outer ends of the internal ribs and provided with a peripheral substantiallyhelical rib having a portion thereof formed of greater diameter than the outer ends of the internal ribs and movable between said internal ribs and the exit of the feeding-passage, substantially as and for the purpose specified.

4:. A cutting apparatus comprisinga frame provided with a feeding-passage having internal ribs, a plate having cutting edges and openings for the passage of the material, and a forcing member rotating Within the feedingpassage and having one extremity extended beyond the outer ends of the internal ribs and provided with a peripheral substantially helical rib having a portion thereof formed of greater diameter than the outer ends of the internal ribs and movable between said inter- 5. A cutting apparatus comprising a frame provided with a feeding-passage and a hub alined with the feeding-passage and formed with a peripheral enlargement, a forcing member arranged within the feeding-passage, and a handle for actuating the forcing member, said handle being provided with an openended and open-sided socket for receiving the peripheral enlargement, and having shoulders for engaging'opposite surfaces of said enlargement and preventing endwise movement of the handle, substantially as and for the purpose set forth. r

. 6. A cutting apparatus comprising a frame provided with a feedingpassage and a hub alined with the feeding-passage and formed with'a peripheral enlargement, a forcing member arranged within the feeding-passage and having one extremity extended beyond said enlargement and formed angular in cross-section, and a handle provided with an open-ended and open-sided socket for receiving the peripheral enlargement and having shoulders for engaging'opposite surfaces of said enlargement and of Onondaga, in the State of New York, this 23d day of April, 1901.
